Kerdi flush with wall. Can I just put a layer of drywall paper over it?
The middle part (only) is flush with the wall. I'm thinking of putting a layer of drywall paper over it and then mud. Will it work or do I need something else to protect the kerdi board?
EDIT: I'll learn my lesson one day to give Reddit all the backstory. 😂 This is a storage room, there is a bathroom on the other side. We're looking at the back of a shower niche. There is a single piece of kerdi under that second layer, that's the back of the niche. My guess is he added that second layer to imitate the missing wall behind and ensure it's all flush. I probably could try to remove it, but since I can mud over it apparently, I'll do that.
